Abstract

Protein synthesis in eukaryotes is regulated by diverse reprogramming mechanisms that expand the coding capacity of individual genes. Here, we exploit one such mechanism, termed -1 programmed ribosomal frameshifting (-1 PRF), to engineer ligand-responsive RNA switches that regulate protein expression. First, efficient -1 PRF stimulatory RNA elements were discovered by in vitro selection; then, ligand-responsive switches were constructed by coupling -1 PRF stimulatory elements to RNA aptamers using rational design and directed evolution in Saccharomyces cerevisiae. We demonstrate that -1 PRF switches tightly control the relative stoichiometry of two distinct protein outputs from a single mRNA, exhibiting consistent ligand response across whole populations of cells. Furthermore, -1 PRF switches were applied to build single-mRNA logic gates and an apoptosis module in yeast. Together, these results showcase the potential for harnessing translation-reprogramming mechanisms for synthetic biology, and they establish -1 PRF switches as powerful RNA tools for controlling protein synthesis in eukaryotes.

  • Two stabilizing RNA elements (Zika virus-derived xrRNA1 dumbbell and evopreQ1 pseudoknot) led to a robust increase in bcgRNA UMI counts, while protein knockdown was indistinguishable among six structures.

    “While protein knockdown was indistinguishable for all six structures (Fig. 5b,c and Extended Data Fig. 9b), we found that two elements (Zika virus-derived xrRNA1 dumbbell33; evopreQ1 pseudoknot34) led to a robust increase in bcgRNA unique molecular identifier (UMI) counts (Fig. 5d).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
